Here's how it will work:
IrRoamingWithSpeedControl.bs2 already uses infrared to check for obstacles between
each pair of pulses to the servos. The key to detecting incoming messages from the
remote is to check the IR detectors before using the
objects. If the program checks to find out if IR is detected before checking for obstacles,
it can easily detect an incoming message from the remote. Here are the steps that should
be executed inside the main routine's

By pressing the any button, you will interrupt the Boe-Bot's roaming.
Then, you will use the numeric keypad to type in the new percent-speed.
To make the Boe-Bot resume roaming at the new speed, press the ENTER button.
Before testing for objects with the Boe-Bot's IRLED headlights, test the IR
detector's output pin to see if a signal is coming from the remote.
Check the IR detectors.

Open IrRemoteKeypad.bs2.
Save a copy of it as RoamingWithRemoteSpeedControl.bs2.
